Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During flight over lake Michigan at 13,000 feet, the pilot noticed that the throttle, mixture and propeller controls to one of the engines began binding. The controls to the other engine remained normal. He descended to 9000 feet and continued at reduced power. After landing, an investigation revealed that the exhaust stack was loose at a slip joint where it passed through the firewall. Hot exhaust gases had damaged the engine controls, an engine mount and the firewall. The aircraft had just come out of maintenance prior to the flight.
